Title: Door construction assembly
Inventor: HALLBERG JOHN ERIK
IPC: E05C19/00
Filed: 1968-01-25
Abstract: 1,217,533. Releasable fastenings. W. H. MINER Inc. 25 Jan., 1968, No. 3890/68. Headings E2A and E2B. A door construction assembly comprising a wall 12 having an opening therein, a door 14 swingable into and out of the opening, a keeper 38 having a planar surface portion 40 and mounted at a free edge portion of the door so that the planar surface portion is oblique to the surface of the door, a leaf member 26 having a planar bearing surface portion 36, and means 24 for hingedly securing the leaf member to the wall to enable the planar bearing surface portion co-operatively to engage ,the planar surface portion of the keeper to restrain the door from swinging out of the opening. In the construction shown the keeper is generally V-shaped with one side presenting the oblique planar surface and the leaf member is generally J-shaped with long and short leg portions thereof being joined by a nose portion, the end part of the long leg portion being secured by hinge pin 34 to a hinge plate constituting the means 24 which in turn is secured to the wall, the short leg portion presenting the planar bearing surface portion. The arrangement is such that the distance between the axis of the hinge pin 34 and the planar bearing surface portion where it merges with the nose portion is greater than the perpendicular distance betwen the hinge pin axis and the planar bearing surface so that there is an over-centre action during fastening and release. As described a plurality of the keepers are secured to the door and there is a corresponding plurality of leaf members which are connected by a bar 22 so that they are all pivoted together into and out of engagement with the keepers. For pivoting the bar a handle 44 is provided which is pivoted to the bar and is arranged to be releasably secured to the outer face of the door 14 by a seal assembly 48. The seal assmbly comprises a seal plate 50 secured to the door by bolts 52 and 54 and a forward projection 56 that is received through a slot 58 formed in the handle 44 an arm 60 which is pivotally mounted on the seal plate is selectively engageable with the handle 44 for retaining the latter against the door; aligned openings 62 and 64 are provided in the arm 60 and a seal plate projection 56 through which a tag or seal band can be fastened. Between the flange 18 of the door and a flange 16 of the walla resilient insulating strip 20 is provided and this enables the door to be moved slightly beyond its normal closed position when the leaf members go over-centre during the fastening action.

[Also in Division F1] An arrangement for closing and opening the two halves of a hopper barge comprises at least one hydraulic and piston combination 1, 2 each in an hydraulic circuit including a pressure medium reservoir 9, a pump 10, connecting pipes 8, 5, 4, 7 between the pump, reservoir and the two chambers in the cylinder 1 on opposite sides of the piston 2, and overflow pipe 12 for returning surplus pressure medium through an adjustable restrictor 13 to the reservoir, a short-circuit pipe 6, and a control member comprising a three-way valve 11 in the pipe 6. In the position of the valve 11 shown in Fig. 1 pressure medium can flow from the left-hand chamber in the cylinder 1 to the right-hand chamber thus allowing the piston 2 to move to the left and the emptied halves of the barge to close under the action of their buoyancies. If it is necessary to use the pump 10 to effect closing, the valve 11 is moved to a second position (see Division F1), while a third position allows the loaded halves to open without-and if necessary with-the assistance of the pump 10.
